In psychoanalytic theory, a defence mechanism is an unconscious psychological operation that functions to protect a person from anxiety-producing thoughts and feelings related to internal conflicts and outer stressors.[1][2][3]
According to this theory, healthy people normally use different defence mechanisms throughout life. A defence mechanism can potentially become pathological when its persistent use leads to maladaptive behaviour such that the physical or mental health of the individual is adversely affected. Among the purposes of ego defence mechanisms is to protect the mind/self/ego from anxiety or social sanctions or to provide a refuge from a situation with which one cannot currently cope.[4]
Examples of defence mechanisms include: repression, the exclusion of unacceptable desires and ideas from consciousness; identification, the incorporation of some aspects of an object into oneself;[5] rationalization, the justification of one's behaviour by using apparently logical reasons that are acceptable to the ego, thereby further suppressing awareness of the unconscious motivations;[6] and sublimation, the process of channeling libido into "socially useful" disciplines, such as artistic, cultural, and intellectual pursuits, which indirectly provide gratification for the original drives.[7]
Some psychologists follow a system that ranks defence mechanisms into seven levels, ranging from a high-adaptive defence level to a psychotic defence level. Assessments carried out when analyzing patients such as the Defence Mechanism Rating Scale (DMRS) and Vaillant's hierarchy of defense mechanisms have been used and modified for over 40 years to provide numerical data on the state of a person's defensive functioning.[8]
